EXPERIMENTAL STUDY OF IMPROVEMENT ON GROUND OF CORAL DEBRIS MIXED WITH MUCKY SOIL BY HIGH VACUUM DENSIFICATION METHOD

摘要: 采用高真空击密法对珊瑚碎屑淤泥质土场地进行地基处理试验研究,通过3遍真空排水和强夯击密循环处理,地下水位累计下降约4 m,施工沉降达68 cm,静力触探试验、平板载荷试验、标准贯入试验结果均表明承载力特征值达150 k Pa以上,影响深度近10 m,孔隙水压力观测反映真空与强夯联合压力差作用效果明显。上述结果表明,高真空击密对珊瑚碎屑淤泥质土处理效果良好。

Abstract: An experimental research on improvement on ground of coral debris mixed with mucky soil by high vacuum densification method ( HVDM) was carried out． Through circulation processing of vacuum drainage and dynamic compaction for three times，groundwater level declined by about 4 m，ground settlement by construction was 68 cm． The improved ground was tested by static cone penetration test ，plate load test，and standard penetration test，the results showed that the bearing capacity value was over 150 kPa and the influence depth was about 10 m． The observation of pore water pressure indicated obvious effect of pressure difference associated with vacuum and dynamic compaction． The tests indicated that HVDM had an excellent effect in the site．
